Ikegami announces UHL-F4000 Separate-Optics Compact Multi-Role 4K HDR Camera

Advanced Imaging Technology
Developed from Ikegami's established high-definition HDL-F3000, the UHL-F4000’s image sensor unit uses three CMOS global shutter elements so there is no rolling shutter distortion even in aerial imaging applications where subjects are constantly moving in parallel. Minimum illumination level in standard operating mode is 0.0015 lux at F12. A focus-assist function places the edge components of the 4K image on a high-definition monitor output feed to guarantee exact focus determination on small HD monitors.

Aerial photographers working from helicopters are increasingly keen to use 4K cameras which tend to be larger and heavier than HD models so require a larger anti-vibration gimbal. In addition, the higher power consumption of 4K cameras causes the internal temperature to rise if a 4K camera is placed in a sealed stabilising unit. This shortens the camera's lifetime and can even lead to sudden failure. The UHL-F4000 overcomes all these challenges. It is a robust and compact camera head with low power consumption delivering very high image quality.

Wide Range Of Applications
Further refinements include a variable contrast control which can handle situations of reduced visibility such as fog or smoke. An image sharpening function is incorporated and a vertical image reversal mode allows the camera to be mounted upside down. The operator can adjust the camera in real time for optimum noise reduction when shooting at night with high gain. A 40 Gbps duplex optical fibre connection communicates between the camera head and base station. These can be positioned up to 10 km apart. The optical fibre can be integrated into one bidirectional core via an optical circulator and passed through a single-core optical rotary joint used for a small gimbal.
The Ikegami UHL-F4000 camera head can also be mounted on a motor-driven pan/tilt head for robotic operation in studio environments. In this configuration, the genlock and remote control cable can be connected to the base station so that the cables do not obstruct camera movement.
Scheduled release date is Q4 2020.
